An elliptic orbit is characterized by the eccentricity, which is how much a planet's distance from its star varies as it carves out a year. Most of the planets in our solar system have relatively low eccentricities, less than about 5 percent (tiny Pluto being a notable exception and considered not really a planet by some astronomers).By contrast, the average eccentricity of extrasolar planets is about 25 percent. And these are not Plutos. They are typically more massive than Jupiter.Some have eccentricities of 80 percent, which is as high as the crazy orbits of some comets in our solar system.Marcy and others detect extrasolar planets - most often induce in their host stars. This planet-star swing dance might seem to be more noticeable when the planets orbit is highly eccentric, but Marcy said that is not true. As more and more planets are found, it appears that high eccentricities are common, making our solar system more the exception than the rule
